The fluorescent lights don t shine very brightly when they are first turned on

is the action time of the starter.

The working principle of the fluorescent lamp is to excite the mercury vapor in the lamp to emit light (so remember to open the window for ventilation after the fluorescent lamp is broken, otherwise it will cause mercury poisoning).

For mercury vapor to be excited, it requires a very high voltage; After excitation, only a very low voltage is sufficient (which is one of the reasons why fluorescent lamps are more energy-efficient than incandescent lamps).

The solution to the contradiction of the voltage difference before and after excitation is the self-inductance of the starter. Inside the starter is a neon bubble (neon gas glows red when excited, and you can see the red light in the starter every time you turn on the light, right?) There is also a self-sensing filament.

The mercury vapor luminescence is excited by the high voltage generated by the self-induction, and the self-inductance filament is disconnected and the voltage is reduced to maintain the normal luminescence.

Self-perception takes a certain amount of time, so fluorescent lamps cannot be lit immediately with the pull of a switch like incandescent lamps. That's why it's a bit of a wait.

The fluorescent lamp is made of phosphor as the light source, when the lamp is turned on, the phosphor will be heated and sublimated into fluorescent steam in the lamp, and the two levels of current are distributed on both sides of the lamp, then the current will break through the fluorescent vapor to form a loop, the arc light becomes the light we see under the hidden light of the fluorescent vapor, the problem of the landlord is in the link where the phosphor becomes fluorescent vapor, because this process takes time, and the phosphor gradually becomes fluorescent vapor The brightness also increases.

There is a transient homeostatic transition to a steady state.

The lights are not working, it's time to change!

When the fluorescent lamp is just turned off, it will continue to emit a faint light (pale green or off-white), which is a normal phosphor afterglow phenomenon that will disappear for about a minute. If the light glows faintly long after the light is turned off, check whether the switch is incorrectly connected in the neutral line.

First, the switch controls the neutral line. This is one of the more common reasons, the electrical line switch controls the neutral line, or the electrical box enters the neutral line to fire back. The switch controls the neutral line, which is still connected to the fixture and emits a shimmering light.

Solution: Adjust the wiring so that the switch controls the live wire.

Second, the double control switch has an incorrect connection. There are several ways to connect the dual control switch, and if the wrong connection is used, the light will turn off and turn on slightly.

Solution: Install the normal control live wire connection and rewire.

3. The switch has an indicator light and uses an electronic switch. There is an indicator light inside the switch. When the light goes out, there will be a weak current flowing through. For example, lamps and lanterns use electronic switches, such as infrared, voice, remote control switches, etc. It will also light up when the lights are out.

Solution: Change the switch.

The two ends of the lamp are shining, but the middle is not lit. This is usually due to the aging of the lamp or the difficulty of starting up due to the voltage being too low. The heat dissipation of the lamp can be treated and the configuration ballast can be replaced.

or starter, or adjust the voltage to maintain the rating.

The light is flickering or there is a rolling light band in the tube. This kind of phenomenon is generally caused by the link of the starter or ballast is not bright, and sometimes it is caused by the poor quality of the lamp or the temporary phenomenon of the new lamp.

There are many reasons why the fluorescent lights in your home are broken, it can be the lack of a regulator, power fluctuations, aging fluorescent lights. At the end of the lamp's life, the phenomenon is that one or both ends of the lamp are black, with a large black range, or the surrounding surface of the lamp is black. The electric light does not emit light when it is started, or there is a short flashing light, and it does not discharge and turns off directly.

The ends of the lamps all emit a dark orange glow and do not discharge. The reason is that after being used long enough, the phosphorescent paint around both electrodes fades at the same time or at one end. At this time, it is necessary to replace the fluorescent lamp with a new one.

The bulb is not used for a long time, much less than the rated use time. Because the supply voltage is not suitable, there are too many switches, resulting in over-starting, or poor pin contact. Is the processing method to confirm the data of the gimbal device?

Minimize the number of switches and carefully inspect all parts and accessories that come into contact. Discoloration at the end of the lamp, with dark spots, black rings, or brown rings appearing in a wide area. The cause of this phenomenon is the condensation of mercury in the lamp, the stabilizer and lamp are not suitable, or the light is not of good quality.

In addition, it is necessary to measure whether the voltage is consistent and whether the contact parts are in good contact. The ends of fluorescent lamps are dim and not bright. Because the capacitor in the guihui device is short-circuited, there is no contact, or there is an error in the wiring.

The way to deal with it is to get a new machine. If it's a newly installed lamp, check the wiring carefully.

Fluorescent lights are difficult to start, and the flash memory time when the off switch is activated is too long, and if it continues, the lights will quickly break. The reason for this malfunction may be that the fluorescent lamp has been in use for a long time and is nearing the end of its life. If this happens to the new lamp, it is because the quality of the lamp is not high, or the guihui device is outdated and no longer functional.

The power supply voltage is too low or the temperature around the bulb is too low to start. When maintaining, if it is a new lamp, it should be installed on other better lamps for testing. If it is still difficult to start, there is a problem with the light.

For example, if it proves to be a good lamp, the regulator needs to check the machine and the stabilizer, or increase the voltage through the regulator, or wait until the room temperature reaches normal temperature before using it. The brightness of fluorescent lamps is reduced, i.e. the brightness is significantly lower than that of the usual fluorescent lamps. The main causes of this failure are improper use of the bulb, too much dust has accumulated on the outside of the bulb, the temperature outside the bulb is too low or too high, and the power supply voltage is too low.

In addition to using this problem incorrectly, there are several other situations that can be solved in vain.

The noise emitted by the fluorescent lamp stabilizer is mainly due to improper installation or the vibration of the iron plate inside the stabilizer, the inconsistent specifications of the fluorescent lamp and the stabilizer, the heat of the stabilizer itself, and the local short circuit of the gimbal itself. The way to deal with this malfunction is to use a soft rubber pad stabilizer so that the sound is a little less. It is also possible to double-check the wiring for errors, and then remove the stabilizer and pass it separately through the rated voltage, checking if there is a problem with the stabilizer itself.

First check whether it is caused by poor contact, first rotate the lamp, then press the contact between the lamp electrode and the lamp holder electrode, and rotate the starter to make the contact between the motor and the base electrode firmly, if you adjust it according to the above steps or can not start, it means that it is not a problem of poor contact.

The fluorescent lamp cannot be started should be caused by insufficient charging, and it must be ensured that it is charged in full sunlight.

You should check with an electrician, who can check that there is a problem and then repair it.

At the beginning, because the temperature of the filament is lower, the resistance is less, and the power of the lamp is small, and after a period of time, the temperature of the filament rises, the resistance becomes larger, and the power of the bulb becomes larger, so the bulb becomes brighter.

Generally, fluorescent lamps have a characteristic, that is, they are not very bright when they are just pointed, and they reach the maximum brightness after a while, this is because the fluorescent lamp is emitted by the mercury vapor in the lamp to hit the phosphor, and when it is just started, the mercury vapor has not been completely vaporized, and the brightness of the lamp can only reach normal after it is completely vaporized, and this phenomenon is more obvious in winter.

This is also the case with energy-saving lamps, which use inductive ballasts and flash a few times when they are turned on because they need to be turned on. Electric trace ballasts fluorescent lamps do not have this problem. If it's not a fluorescent lamp, it's probably going to be damaged!
